Sequential hypothesis testing for axion haloscopes
Abstract The goal of this paper is to introduce a novel likelihood-based inferential framework for axion haloscopes that is valid under the commonly applied “rescanning” protocol. The proposed method enjoys short data acquisition times and simple tuning of the detector configuration. Local statistical significance and power are computed analytically, avoiding the need for burdensome simulations. Adequate corrections for the look-elsewhere effect are also discussed.
Wissenschaftliches Publizieren: Die fatale Folge von Sensationsmeldungen
In den vergangenen Jahren verkündeten Wissenschaftler in der Astroteilchenphysik und Kosmologie eine Reihe von großen Entdeckungen. Die Liste umfasst überlichtschnelle Neutrinos, Gammastrahlen aus dem Zerfall von Teilchen der Dunklen Materie und sogar Spuren von Gravitationswellen in der kosmischen Hintergrundstrahlung – hervorgerufen durch eine Phase rascher Expansion des frühen Universums.
Reproducibility: Don't cry wolf
Illustration by David Parkins The past few years have seen a slew of announcements of major discoveries in particle astrophysics and cosmology. The list includes faster-than-light neutrinos; dark-matter particles producing γ-rays; X-rays scattering off nuclei underground; and even evidence in the cosmic microwave background for gravitational waves caused by the rapid inflation of the early Universe.
